The project objectives are monitoring long term trends. Sampling was performed at Slaggo from 1986 (on going) and at Broa between 1989-1996. The data were collected on cruises with a research vessel. The data are quality inspected. Checks were made by manual control. Data from simultaneous biological sampling are stored in BIOMAD at the Department of Systems Ecology.
